What is that?

I turned once again to Fred Heath for the identity of this weird and wonderful caterpillar. He wrote:

It’s a Red-spotted Purple. There is a decent photo of the adult and caterpillar in that Butterflies of SE AZ fold-out brochure [available in the visitor center]. Although the caterpillar is a good mimic of bird poop, the adults get protection by mimicking unpalatable Pipevine Swallowtail. Willows are their host plant in Sabino, so my guess is that it was found along the road up where the Sabino Creek is nearby.
